液压混合动力履带车辆联合制动模糊控制

To achieve the braking stability of hydraulic hybrid tracked vehicle with combined braking system, the fuzzy control method based on braking moment distribution principle is proposed. First, the models of energy regeneration braking system, mechanical friction braking system and vehicle dynamical model are developed by using MATLAB. Then, the fuzzy controller with braking moment distribution coefficient as control variable is designed, and the fuzzy variables inference rules are put forward. The simulation model of control system is set up, and the braking process is simulated in different braking intensities. The simulation results indicate that the combined braking fuzzy control system can recover braking energy efficiently, and improve braking stability of the tracked vehicle significantly in comparing to PID control.
